sound help

ummmmmm, this may not be c++ programming maybe its windows, i dunno but can somebody tell me why it doesn't work

Code:

---

#include <iostream>
#include <windows.h>
#include <mmsystem.h>

main()
{
        PlaySound("c:/sound.wav", NULL, PND_ASYNC); // This plays the file in the backround
        Sleep(400);
        return 0;
}

---

it gives me this error
C:\Program Files\DevStudio\SharedIDE\bin\sound test.cpp(9) : error C2065: 'PND_ASYNC' : undeclared identifier


I remembered to use code tags, yay!

It's SND_ASYNC, not PND_ASYNC.

Isn't it supposed to be

C:\soundwav

instead of C:/sound.wav

don't hit me.

Nope. The file's name is sound.wav so you open sound.wav

ditto

ummmmmm i dunno, none of those things seem to work

here's my current code

Code:

---

#include <iostream>
#include <windows.h>
#include <mmsystem.h>
main()
{
        PlaySound("c:/sound.wav", NULL, SND_ASYNC); // This plays the file in the backround
        Sleep(400);
        return 0;
}

---

thanks

Try this:

Code:

---

#include <iostream>
#include <windows.h>
#include <mmsystem.h>
main()
{
        PlaySound("c:\\sound.wav", NULL, SND_ASYNC); // This plays the file in the backround
        Sleep(400);
        return 0;
}

The function also returns an error code, TRUE if successfull and FALSE if unsuccessfull. Maybe you could try checking that with some debug code. If that still doesn't work, make sure your speakers are plugged in and the volume is turned up, maybe the sound is playing but you are just not hearing it (checking the error code would help with this, you'd be able to see some output that the function returned TRUE indicating success even though you might not be able to hear anything).

even with that new code it doesn't work

gives me these:

sound test.obj : error LNK2001: unresolved external symbol __imp__PlaySoundA@12
Debug/sound test.exe : fatal error LNK1120: 1 unresolved externals

Ok, now we get to the heart of the problem. It would have been extremely usefull to have known this at the start but perhaps you never got far enough to see that message before. You need to modify your project so you add in the Winmm.Lib (I think that's the one) when you link.

ummmmm lol I'm afraid I don't know how to link it to my project

do you mean just include it at the top?

No, and I don't know what compiler version you are using so I'm not sure my instructions would be exact. I use Microsoft Visual Studio 6.0 and these are the steps you would go through in that version:

1) Go to the Project menu option.
2) Click on the Settings option.
3) You will get a "Project Settings" window pop-up, look in the right hand portion of the window and you should see several tabs, one of which says "Link", click on that "Link" tab.
4) The right hand portion of the "Project Settings" window will change and there will be an area labeled "Object/library modules:". Click in that area, where all the *.lib files are located, and then hit the End key to go to the end of all those files. At the end of the list of library files you need to type in "Winmm.lib" to add it to your project.
5) Click on the "OK" button of the "Project Settings" window.
6) Rebuild your project and the new library you just added should eliminate the error you were getting.

If you have a different compiler your steps will likely be different but there should be some Menu options you can go through to get to your project settings. You may have do do some seaching. It sounds like you are using some version of the Microsoft Visual Studio.

If you're playing from a file on disk (which you are) then you also need to include SND_FILENAME:

Code:

---

PlaySound("sound.wav",NULL,SND_FILENAME | SND_ASYNC);
